Made from high speed steel (HSS) with a bright uncoated finish, this bit is built for general-purpose drilling in a wide range of materials. The two-flute spiral design features a fast spiral type and a web-thinned, tapered web configuration that improves chip evacuation and reduces feed pressure at the point. The straight cylindrical shank measures 1\/4 inch in diameter and 1.25 inches in length, making it compatible with standard drill chucks. This is an ASME B94.11M-compliant bit intended for use by machinists, fabricators, maintenance technicians, and general tradespeople.\u003c\/p\u003e\u003cp\u003eThe C03073 is suited for drilling aluminum as its primary workpiece material, though its general-purpose HSS construction handles a broad range of soft to medium-hardness metals and plastics. With an overall length of 4 inches and a flute length of 2.75 inches, this jobber-length format fits standard benchtop drill presses, handheld electric drills, and magnetic base drills. It is sold individually and is part of the Cleveland Series 2012 jobber drill line.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter E size: 0.2500 inches (1\/4 inch) diameter with a tolerance of -0.0007 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced thrust and cleaner entry\u003c\/li\u003e\n\u003cli\u003eFast spiral, two-flute design promotes efficient chip removal, especially in aluminum\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with bright uncoated finish for general-purpose use\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank (1\/4 inch diameter) fits standard chucks without adapters\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B94.11M standards, Series 2012\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in standard 3-jaw chucks on drill presses, hand drills, and similar equipment accepting 1\/4-inch straight shank tooling.

Secure the shank fully in the chuck and verify the bit runs true before engaging the workpiece. Always power down and de-energize or lock out any drill press or power tool before changing bits. For best results in aluminum, use appropriate cutting fluid and clear chips frequently given the absence of coolant-through capability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Fast)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2012\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B94.11M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C03073\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51719197360434,"sku":"C03073","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/693fe7daf63bc4e3c34d665d98901597.jpg?v=1788558063","url":"https:\/\/voomisupply.com\/products\/cleveland-c03073-jobber-drill-bit-letter-e-1-4-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
